The 10-24 is very similar, they're both very similar. The Tokina is faster, so it's better for low light capabilities. Although, also note that the Nikkor will get you that nit wider plus it has the build in Nikon AF motor. Remember that sometimes third party lenses won't always work perfectly on newer cameras, for instance, as Ken Rockwell noted in his D7000 review the 105mm Sigma macro lenses don't work on the D7000, so it's a bit of a gamble when purchasing 3rd party. Personally, I'm a bit of a Nikon fanboy and only buy the Nikkor lenses, but these are fine choices.
To post your images, I'd start a new thread. This thread (Which was originally created to help you choose a new camera) is getting a tad bit off topic. We're all looking forward to seeing those images!
